摘要
The invention relates to a process for obtaining a ceric oxide of controlled particle size distribution. …??The invention also relates, as new industrial products, to a ceric oxide with new morphological characteristics. …??The process is characterised in that it consists in hydrolysing an aqueous solution of a cerium(IV) salt in an acidic medium in the presence of an aqueous colloidal dispersion of a cerium(IV) compound, in separating off the precipitate obtained and in then subjecting it to a heat treatment. …??The said process makes it possible to obtain a ceric oxide of a fine and narrow particle size distribution.
